Porcine reproductive and respiratory syndrome virus (PRRSV) is an important pathogen that has caused huge economic losses in the global swine industry. The advent of molecular farming has provided a cost-effective strategy for the development of transgenic plants as bioreactors to produce recombinant proteins. In this study, transgenic potato expressing GP5 protein of PRRSV was produced by Agrobacterium-mediated transformation, and confirmed using Southern blot and RT-PCR analyses. Recombinant GP5 protein was detected by ELISA and Western blot analyses. Mice immunized with transgenic potato extracts generated both serum and gut mucosal-specific antibodies, although low levels of neutralizing antibodies were elicited. This study provides a new approach for the production of vaccines against PRRSV.
